Planarians belong to the superphylum Lophotrochozoa, phylum Platyhelminthes, subphylum Catenulidea, class Rhabditophora (some consider the artificial grouping Turbellaria), order Tricladida, suborder Paludicola, and families Dugesiidae, Kenkiidae, Planariidae, and :// Planarian, any of a group of widely distributed, mostly free-living flatworms of the class Turbellaria (phylum Platyhelminthes).
Planaria is the name of one genus, but the name planarian is used to designate any member of the family Planariidae and related families. Most planarians occur in fresh water and are sometimes seen in large masses; some species are marine, others are :// Chapter 33 Invertebrates Lecture Outline.
Turbellarians are nearly all free-living (nonparasitic) and most are marine. Planarians, members of the genus Dugesia, are carnivores or scavengers in unpolluted ponds and streams.
In most spiders, gas exchange is carried out by book The size of this planarian varies with the season. Smaller forms are more prevalent in early spring; larger or mature forms are evident throughout the remainder of the year.

Planarians and other flatworms lack organs specialized for gas exchange and circulation. Their flat shape places all cells close to the surrounding water and fine branching of the digestive system distributes food throughout the Discussion.
The “parent” Dugesia flatworm obtained from the stock culture successfully regenerated into two complete planarians with eyespots, auricles, and developed heads and tails after being decapitated. This conclusion is based on close observation of both planarians after 7 days of incubation.

WIREs Dev Biol 2(3)– Google Scholar Platyhelminthes (flatworms) have captivated the imagination of biologists for centuries. Indeed, planarian flatworms were used as experimental models decades before Caenorhabditis elegans became known as ‘the worm’.

Like vertebrates, invertebrates are classified based upon their body structure, life cycle, and evolutionary history. From the National Geographic book, Animal Encyclopedia, Animal Facts Planarians are free-living flatworms best known for their amazing ability to regenerate.
